'''''Agrostis''''' ('''Bent''' or '''Bentgrass''') is a genus of over 100 species belonging to the grass family [[Poaceae]].
Some species of bents are commonly used for [[lawn]] grass. This is a desirable grass for [[golf]] course tees, fairways and greens.
Bentgrass is used in turf applications for its numerous advantages: it can be mowed to a very short length without damage, it can handle a great amount of foot traffic, it has a shallow root system that is thick and dense allowing it to be seeded and grow rather easily, and it has a pleasing, deep green appearance.

Beloperone (name refers to the arrow-shaped connective). Acanthaceae. Hothouse evergreen shrubs of the Justicia group, rarely seen in cult, and apparently not in American trade. Lvs. entire: fls. usually red or purple, mostly in showy-bracted axillary or terminal clusters; corolla-tube narrow, often long, the limb 2- lipped; stamens 2, affixed on the tube; style filiform, entire or slightly 2-lobed: fr. an oblong or ovoid caps. — About 30 species inhabiting Trop. Amer., of which 2 or 3 are listed as cult, plants. B. violacea, Planch. & l.irnl., has lanceolate-acuminate Lvs. and violet-purple fls. B.M. 5244. B. oblongata, Lindl., has oblong- lanceolate Lvs. and axillary spikes of rose-purple fls. B.R. 1657. A recent species is B. angustiflora, Stapf, resembling B. violacea. with oblong-elliptic Lvs. and a very narrow corolla-tube with a violet-purple limb.

Spikelets 1-fld.; glumes about equal, acute; lemma shorter and more delicate than the glumes, sometimes awned from the back, palea usually shorter than the lemma, often small or wanting.—Species about 100, distributed over the entire world, especially in the north temperate zone. The genus comprises several forage and lawn grasses and a few ornamental, the panicles being used for bouquets. A nebulosa is excellent for dry bouquets. A. elegans of gardens is an Aira.

'''Creeping Bentgrass''' (''Agrostis stolonifera'' L.; syn = ''Agrostis palustris'' Huds.) is the most commonly used species of ''Agrostis''. It is cultivated almost exclusively on golf courses, especially on putting greens. Creeping Bentgrass aggressively produces horizontal stems, called stolons, that run along the soil's surface. These stolons allow creeping bentgrass to form dense stands under conducive conditions and out-compete bunch-type grass and broadleaf weeds. As such, if infested in a home lawn, it can become a troublesome weed problem. The leaves of the bentgrass are long and slender.

'''Velvet Bentgrass''' (Agrostis canina L.) gets it name for the velvet appearance that this grass produces. It has the finest texture of all the bent grasses. This grass was used in Europe for estate lawns and golf courses because it could be cut so short. This bent grass does require more upkeep and maintenance that the Creeping variety and because of this has been overlooked as a practical turf for current golf courses. This variety also has a lighter color than the two other varieties.
